The prestress technology is widely used in modern building and bridge engineering, which can improve the bearing capacity and deformation resistance of structures and extend the service life of buildings. However, the performance of prestress materials, especially the performance of slow-bonding materials, is crucial for the safety and stability of structures.

[0003] Chinese Patent CN118999870B, authorized and announced on February 28, 2025, discloses a building slow-bonding prestress detection device, system and its use method.

The support cylinder is coaxially arranged with the anchor seat, and a plurality of telescopic oil cylinders are arranged circumferentially on the outer wall. The output end of the telescopic oil cylinder is perpendicular to the limiting sleeve plate and can adjust the distance between the limiting sleeve plate and the support cylinder. A plurality of selective locking sleeves cooperating with steel strands are arranged in the inner side of the support cylinder in an arranged manner, and each selective locking sleeve is penetrated by a single steel strand.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Embodiment 1, please refer to Figures 1-3 , a building slow-bonding prestressed intelligent detection device and detection method, including: Detection chamber 100, the inner side wall of the detection chamber 100 is equipped with a threaded rod 200 through threading. A movable rod 300 is rotatably connected to the side of the threaded rod 200. A sliding rod 500 is assembled at the bottom of the movable rod 300. The sliding rod 500 penetrates the detection chamber 100 and is in a sliding connection state with the detection chamber 100. A clamping seat 400 is assembled on the side of the movable rod 300. One end of the object to be detected is installed in the shaft seat, and the other end is inserted into the detection chamber 100. Rotate the threaded rod 200, and the movable rod 300 rotatably connected to the threaded rod 200 is simultaneously slidably connected to the detection chamber 100 through the sliding rod 500. That is, the movable rod 300 is restricted by the sliding rod 500. Thus, when the threaded rod 200 rotates and moves simultaneously, it drives the movable rod 300 to move horizontally, so that the movable rod 300 drives the clamping seat 400 to lock the object to be detected. The main control terminal drives the telescopic oil cylinder, records the value of the displacement sensor until a detection is completed and then stops; An adjustment disc 601 is assembled on the side of the threaded rod 200. An internal through hydraulic chamber one 602 is assembled inside the detection chamber 100. A force receiving rod one 603 is slidably connected to the side of the hydraulic chamber one 602 through a piston. When the object to be detected is an object with a certain elasticity, the clamping seat 400 continues to move. At this time, the adjustment disc 601 assembled on the side of the threaded rod 200 can squeeze the force receiving rod one 603, so that the force receiving rod one 603 slides into the hydraulic chamber one 602. And the hydraulic chamber one 602 is a chamber filled with oil inside. At this time, the force receiving rod one 603 can squeeze the oil in the hydraulic chamber one 602.

[0022] A spring one 604 is assembled on the side of the force receiving rod one 603. One end of the spring one 604 away from the force receiving rod one 603 is assembled on the inner wall of the hydraulic chamber one 602. A hydraulic chamber two 605 is assembled on the side of the movable rod 300. A hose one 606 is assembled between the hydraulic chamber two 605 and the hydraulic chamber one 602. A push rod one 607 is slidably connected to the side of the hydraulic chamber two 605 through a piston. A limiting rod 608 is assembled on the side of the push rod one 607. The limiting rod 608 is located inside the clamping seat 400, and the limiting rod 608 penetrates the clamping seat 400. When the force receiving rod one 603 squeezes the oil in the hydraulic chamber one 602, the oil in the hydraulic chamber one 602 moves into the hose one 606. The oil in the hose one 606 is squeezed and can flow into the hydraulic chamber two 605, so that the oil originally stored in the hydraulic chamber two 605 squeezes the push rod one 607, driving the push rod one 607 to move sideways, so that the push rod one 607 drives the limiting rod 608 fixedly connected to it to move sideways. At this time, the clamping seat 400 moves sideways to clamp. And the limiting rod 608 assembled on the clamping seat 400 extends out of the clamping seat 400, and can further clamp the object with a certain elasticity. It reduces the possibility of sliding friction between the object and the clamping seat 400 and improves the accuracy of the detection result.

[0023] After the detection operation is completed, the adjustment disk 601 is reset under the action of the threaded rod 200. At this time, the restriction of the adjustment disk 601 on the first force-bearing rod 603 is reduced, so that the first force-bearing rod 603 is reset under the action of the first spring 604. Similarly, the limiting rod 608 and the clamping seat 400 are reset, facilitating the next use of the device.

[0024] An adsorption assembly 700 for adsorbing the object to be detected and a monitoring assembly 800 for monitoring cracks are assembled inside the detection chamber 100.

[0025] During use, one end of the object to be detected is installed in the shaft seat, and the other end is inserted into the detection chamber 100. The threaded rod 200 is rotated, and the moving rod 300 rotatably connected to the threaded rod 200 is simultaneously slidably connected to the detection chamber 100 through the sliding rod 500. That is, the moving rod 300 is restricted by the sliding rod 500. Thus, during the rotation and simultaneous movement of the threaded rod 200, the moving rod 300 is driven to move horizontally, causing the moving rod 300 to drive the clamping seat 400 to lock the object to be detected. The main control terminal drives the telescopic oil cylinder, records the value of the displacement sensor until a detection is completed and then stops. When the object to be detected is an object with a certain elasticity, the clamping seat 400 continues to move. At this time, the adjustment disk 601 assembled on the side of the threaded rod 200 can squeeze the first force-bearing rod 603, causing the first force-bearing rod 603 to slide into the first hydraulic chamber 602. The first hydraulic chamber 602 is a chamber filled with oil. At this time, the first force-bearing rod 603 can squeeze the oil in the first hydraulic chamber 602, causing the oil in the first hydraulic chamber 602 to move into the first hose 606. The oil in the first hose 606 is squeezed and can flow into the second hydraulic chamber 605, causing the oil originally stored in the second hydraulic chamber 605 to squeeze the first push rod 607, driving the first push rod 607 to move sideways, causing the first push rod 607 to drive the limiting rod 608 fixedly connected to it to move sideways. At this time, the clamping seat 400 moves sideways to clamp, and the limiting rod 608 assembled on the clamping seat 400 extends out of the clamping seat 400, enabling further clamping of the object with a certain elasticity. After the detection operation is completed, the adjustment disk 601 is reset under the action of the threaded rod 200. At this time, the restriction of the adjustment disk 601 on the first force-bearing rod 603 is reduced, so that the first force-bearing rod 603 is reset under the action of the first spring 604. Similarly, the limiting rod 608 and the clamping seat 400 are reset.

[0026] Example 2, please refer to Figures 1-6, on the basis of the first embodiment, the adsorption assembly 700 includes a fixed rod 701 assembled at the bottom of the moving rod 300. A rotating block 702 is rotatably connected to the side of the fixed rod 701. A power rod 703 is assembled at the bottom of the first push rod 607. One end of the rotating block 702 is fixedly connected to a first connecting rod 704. The first connecting rod 704 is located on the side of the power rod 703 and is in an articulated state with the power rod 703. When the first push rod 607 moves relative to the clamping seat 400, the first push rod 607 can drive the power rod 703 fixedly connected thereto to move toward the side close to the clamping seat 400, so that the power rod 703 drives the first connecting rod 704 articulated thereto to move toward the side close to the clamping seat 400.

[0027] The other end of the rotating block 702 is fixedly connected to a second connecting rod 705. A suction cup 706 and a pneumatic chamber 707 are respectively assembled on the side of the clamping seat 400. When the clamping seat 400 locks the object to be detected, the suction cup 706 assembled on the clamping seat 400 can preliminarily adsorb the object to be detected.

[0028] A transmission rod 708 is slidably connected to the side of the pneumatic chamber 707 through a piston. The transmission rod 708 is located on the side of the second connecting rod 705 and is in an articulated state with the second connecting rod 705. When the first connecting rod 704 moves toward the side close to the clamping seat 400, as Figure 6 shown in the figure, the first connecting rod 704 can drive the rotating block 702 to rotate clockwise by a certain angle, so that the rotating block 702 drives the second connecting rod 705 fixedly connected thereto to rotate clockwise by a certain angle. The second connecting rod 705 drives the transmission rod 708 articulated thereto to move away from the pneumatic chamber 707. And the transmission rod 708 is slidably connected to the pneumatic chamber 707 through a piston, so that the transmission rod 708 extracts the residual gas in the suction cup 706 into the pneumatic chamber 707 through the pneumatic chamber 707. The adsorption effect of the suction cup 706 on the object to be detected is improved, and the stability of the device during use is improved.

[0029] During use, on the basis of the first embodiment, when the clamping seat 400 locks the object to be detected, the suction cup 706 assembled on the clamping seat 400 can preliminarily adsorb the object to be detected. When the first push rod 607 moves relative to the clamping seat 400, the first push rod 607 can drive the power rod 703 fixedly connected thereto to move toward the side close to the clamping seat 400, so that the power rod 703 drives the first connecting rod 704 articulated thereto to move toward the side close to the clamping seat 400. At this time, as Figure 6As shown in the figure, the connecting rod 704 can drive the rotating block 702 to rotate clockwise by a certain angle, so that the rotating block 702 drives the connecting rod 705 fixedly connected thereto to rotate clockwise by a certain angle. The connecting rod 705 drives the transmission rod 708 hinged thereto to move away from the air pressure chamber 707. The transmission rod 708 is slidably connected to the air pressure chamber 707 through a piston, so that the transmission rod 708 extracts the residual gas in the suction cup 706 into the air pressure chamber 707 through the air pressure chamber 707.

[0030] Embodiment 3. Please refer to Figures 1-8 , on the basis of Embodiment 1 and Embodiment 2, the monitoring assembly 800 includes a hydraulic chamber 801 assembled on the top of the second hydraulic chamber 605. The hydraulic chamber 801 is assembled at the top position of the second hydraulic chamber 605 and is communicated with the second hydraulic chamber 605. When the oil in the second hydraulic chamber 605 moves, part of the oil can flow into the hydraulic chamber 801 communicated with the second hydraulic chamber 605, squeezing the oil originally stored in the hydraulic chamber 801.

[0031] A through hydraulic chamber 802 is assembled on the top of the detection chamber 100. A second hose 803 is assembled between the hydraulic chamber 802 and the hydraulic chamber 801. When the oil originally stored in the hydraulic chamber 801 is squeezed, the oil in the hydraulic chamber 801 flows into the second hose 803, and the oil originally stored in the second hose 803 flows into the hydraulic chamber 802 due to being squeezed.

[0032] The bottom of the hydraulic chamber 802 is slidably connected with an installation rod 804 through a piston. A crack monitor 805 is assembled at the bottom of the installation rod 804. When the oil originally stored in the hydraulic chamber 802 is squeezed, it can drive the installation rod 804 to move downward, so that the installation rod 804 drives the crack monitor 805 assembled thereon to move downward and approach the elastic object to be detected. In this case, the accuracy of the monitoring result is further improved.

[0033] During use, on the basis of Embodiment 1 and Embodiment 2, when the oil in the second hydraulic chamber 605 moves, part of the oil can flow into the hydraulic chamber 801 communicated with the second hydraulic chamber 605, squeezing the oil originally stored in the hydraulic chamber 801, so that the oil in the hydraulic chamber 801 flows into the second hose 803, and the oil originally stored in the second hose 803 flows into the hydraulic chamber 802 due to being squeezed. The oil originally stored in the hydraulic chamber 802 then squeezes the installation rod 804, so that the installation rod 804 drives the crack monitor 805 assembled thereon to move downward and approach the elastic object to be detected.
